Living with Non-distal trisomy 9q

A rare chromosome condition with developmental delay, short stature, intellectual disability, and distinct facial features.

Understanding Non-distal trisomy 9q

Non-distal trisomy 9q is a rare chromosome condition caused by an extra copy of part of the long arm of chromosome 9.

It varies widely from person to person. It mainly involves developmental delay, short stature, intellectual disability, and facial differences such as a small head, broad forehead, low-set ears, and a prominent nose. Differences in the heart, eyes, thyroid, esophagus, brain, and behavior have also been reported. GARD lists onset as newborn.
